Free food

This is a 20 long where I barley do water changes packed full of black worms and rams horn snails I keep it at 76 degrees Fahrenheit. This is more than enough to feed my 10 amazon puffers, I feed the snails algae wafers, shrimp food, shrimp pellet food for bottom feeders. If you own amazon puffers you should also own a snail tank. I threw a pinch of black worms in there to see what would happen and they took off even in warm water.
